Implication

Reduced BRS in hypertension may heighten orthostatic hypotension risk; leaves open causal role and intervention effects in prospective studies.

Population

139 older subjects (75 normotensive, 64 untreated hypertensive) with blood pressure <180 mmHg, taking no cardiovascular medications, recruited from 10 general practices.

Outcome

Baroreflex sensitivity (BRS) determined by high (alphaHF 0.15-0.4 Hz) and low (alphaLF 0.04-0.15 Hz) frequency alpha-index via spectral analysis of 20 min continuous blood pressure and heart rate recordingssurrogate

In older populations, higher systolic blood pressure is associated with reduced baroreflex sensitivity, which may increase the risk of orthostatic hypotension and syncope.
